Title: Electrophotographic suspension developer - contg colour component subjected to flashing process, giving good keeping qualities
Inventor: TSUBUKO KAZUO
IPC: G03G9/13
Filed: 1976-01-05
Abstract: In an electrophotographic suspension developer with a colour (I) and a resin component (II) in a highly insulating liquid vehicle (III) with low dielectric constant, (I) is subjected to a flashing process. This involves kneading an aq. paste of a mixt. of C black (IV) and organic pigments (V) with a soln. in an organic solvent of a resin, which is insol. in (III), which replaces the water around (IV) and (V) with the resin soln., then removing the water and solvent and powdering the resultant mass. The water content of the paste is 40-90 wt.% and the wt. ratio of (V) to (IV) is 1:0 x 1:20. The developer has excellent keeping qualities. The toner image need not contain very much (III) in the transfer process, so that the amt. of (II) to be evapd. can be kept low and rapid transfer and fixing are possible.

Title: Long life filament spinneret plate for melt extrusion - having noble metal nozzle piece let into main plate
Inventor: PIEPER WERNER
IPC: D01D4/02
Filed: 1976-04-03
Abstract: A spinneret plate to produce organic fimanets, particularly of synthetic fibres, uses the melt extrusion process with individual spinning capillaries whose apertures are narrower than their feed passages. The plate has thin insetions of noble metals or their alloys let into the outlet side, these are thin compared with the plate thickness, they contain capillaries and are attached firmly to the plate at least in the annular area around the feed passage. Substances to clean the plate, whether additives to the spun material or aggressive external substances, do not attack the capillary nozzles which therefore have a long service life.

Title: Switching amplifier for control computer - forms control signal pulses which discharge capacitor which operates output switching stage
Inventor: HEINE KARL FRIEDRICH DIPL ING
IPC: H03K17/60
Filed: 1976-09-04
Abstract: The switching amplifier receives a control signal from the control computer control circuit, and, depending on this signal, switches through an output switching stage a corresponding electric load on and off. The control circuit delivers the control signals (e) as a pulse train with short control pulses. Each of these control pulses quickly discharges a charge capacitor (C1) in the switching amplifier and the capacitor (C1) missing voltage serves as control voltage for the output switching stage (T2). A sufficiently long capacitor (C1) charging time keeps its voltage low even during pauses between pulse train pulses. When the control signal (e) ends, output switching stage (T2) switches off after a delay corresponding to the capacitor (C1) charging time. The stage (T2) can be also switched off almost without delay through quick charge of capacitor (C1) through a separate resetting circuit (r).

Inventor: PEICK BENNY
IPC: B65C9/00
Filed: 1976-09-09
Abstract: The device comprises a sharp deflecting edge (11), over which the carrier web (3) is drawn. The detaching movement is assisted by a fender (5) which is in the extension of the label path before detachment and from which the labels (4) are lifted off by sharp-edged supporting rollers (6). This construction allows a high run-through speed of the carrier web (3) through the device, without difficulties in web guidance occurring thereby. At the same time, the labels (4) are still detached reliably from the carrier web (3). <IMAGE>

Title: Prestressed cantilevered structural concrete element - has open channel section at top for cutting and removing wires for reuse (OE 15.4.79)
Inventor: JAEAESKOE VEIKKO
IPC: E04C2/06
Filed: 1978-03-11
Abstract: The cantilevered building element is prestressed by an extruded concrete process, with one or more bottom and top channels drawn through it.

Title: Packaging of foods and drinks - in containers coated internally with polymer carrying enzyme with sterilising action
Inventor: KAJINAMI SHINGO
IPC: B65D81/24
Filed: 1978-04-24
Abstract: Containers for perishable materials, esp. fruit juices, beer, CO2-free drinks, etc., have an internal coating of polymer contg. CO, COOH, anhydrie, epoxy or NCO gps. to which biologically-active enzymes are attached by covalent bonds. The enzyme is attached trhough a non-essential functional gp. consisting of NH2, COOH, OH, phenol, imidazone or sulphhydryl. The enzyme destroys bacteria present by attacking the cell walls, or suppresses reactions between the contents and oxygen, which is used up by the enzyme. Storage life of the contents is increased and they can be packaged without previous sterilisation by heat, e.g. beer can be used without pasteurisation.
